Black and White

N's Castle is a location that appears after you defeat the Elite Four. You encounter Reshiram or Zekrom here depending on the version of the game being played (Reshiram: Pokémon Black; Zekrom: Pokémon White). To go there, you must beat all of the Elite Four members of Unova and then walk into the blue circle around the statue and press A. It will lower and there will be a set of stairs. N's Castle is at the top. You will see N talking to Alder. Dark clouds float above.

When you walk up the black steps, you will see the sages for Team Plasma, and then all of the Gym Leaders (excluding Cilan, Cress, and Chili. Bianca later explains that by the time she got to Striaton City to get them everything at N's Castle was over.), Alder, and Cheren confront the Sages. To the left of the Sages, you will see a flight of steps to lead to the next part of N's Castle.

After 3 flights of stairs, Team Plasma's Shadow Triad will appear and tell you that N is in that room with Zekrom/Reshiram. When you enter, you will see a 3D scene of Zekrom/Reshiram (The one that appears will be under the control of N). Then Reshiram/Zekrom appears with yet another 3D scene. Once you catch it, you will have the ability to switch out one of your Pokémon in your Party for Zekrom/Reshiram and put the other Pokémon in the PC Box. Afterward, N heals your Pokémon and then battles you. When you defeat N, Ghetsis appears, and he battles you. Once you defeat Ghetsis, the game will end with him being taken into custody. N later releases his Reshiram/Zekrom after Ghetsis is taken away. If either of them defeats you, talking to the grunt in the Pokemon league PC/Mart is the only way to return to N's castle, since the man at the front of the League will not let you walk in there to go by foot.

After the game ends, if you battle the Elite Four again, N's Castle is inaccessible, Alder's room is as far as you can go from there on.when the black steps connected the castle to Pokemon league it damaged the Pokemon league and dark clouds are above N's castle with lightning the pillars where damaged by Zeckrom/Reshiram's ability depending on which version because it was done by one under N's control and the one that N controls depends on which version you have and N's castle is the final N battle and the only battle you have with N where N can heal his Pokemon

Black 2 and White 2

Spoiler warning:Plot and/or ending details may follow.

After the player has defeated the Elite Four, Hugh's sister says that she spotted a Zoroark near Victory Road. Upon following it, it leads the player to the ruins of N's Castle, where N has been staying. N takes the player to the spot where he battled against Hilbert/Hilda two years before and challenges the player to a battle against his ZekromB2/ReshiramW2. After he is defeated, he reverts his dragon to its dormant form and gives it to the player so they can revive and capture it in Dragonspiral Tower.

After capturing ZekromB2/ReshiramW2 and Kyurem, and riding the Rondez-View Ferris Wheel with N, he can be rematched at his castle with a full team that differs depending on the season.

Spoiler warning:Spoilers end here.

Trivia

Oddly in Pokémon Black and White 2, N's Castle has only two floors, the first floor is N's Playroom while the second is the Throne Room where he battles Hilbert/Hilda. In Black and White, it has four floors.

This could because the lower two floors were destroyed in whatever event caused the castle's collapse.
